Episode Title:
Virus.
Episode Description:
Jeremy tries to create a virus to destroy the Cortex, however it doesn't work and the group discusses what to do. They decide to lure Laura to the factory. When she gets there the gang explains about X.A.N.A. and the Cortex and that they need her help, which she accepts to give. She easily fixes the problem and they launch the virus and a return to the past. Laura forgets everything, but thanks to a few hidden commands in the virus, the code for the return to the past was altered to exclude Laura, causing her to start having memory flashbacks of her time in the lab. She follows the memories to the sewers. William (who was left on Earth) tries to stall her, but fails, and Laura ends up back at the lab...
